Parameters:
<TraceName> Trace name, string variable, e.g. 'Trc4'. See "Rules for trace
names" in
"Table Area" on page 483. Trace names must be
unique across all channels and diagrams.
<Result> Measurement parameter (string variable); see Table 7-4 .
A query of a wave quantity
'xy'
returns
'xyD<n><Detector>'
, where
<n>
numbers the source
(drive) port, and
<Detector>
denotes the detector setting (
SAM
for a "Normal" (sample),
AVG
for an "AVG Real Imag",
AMP
for
an
AVG Mag Phase
detector). A query of a ratio
'x/y'
returns
'xD<n>/yD<m><Detector>'
, where
<n>
and
<m>
number the
source ports
Example: CALC4:PAR:SDEF 'Ch4Tr1', 'S11'
Create channel 4 and a trace named
Ch4Tr1
to measure the
input reflection coefficient S
11
.
CALC4:PAR:MEAS 'Ch4Tr1', 'a1'
Change the measurement parameter of the trace and measure
the wave quantity a
1
.
CALC4:PAR:MEAS? 'Ch4Tr1'
Query the measured quantity. The response is
'A1D1SAM'
.
Manual operation: See "S-Parameter" on page 437
CALCulate<Ch>:PARameter:MEASure:SENDed <TraceName>, <Result>
Assigns a measurement result to an existing trace. The query returns the result
assigned to the specified trace (no second parameter; see example).
Similar to
CALCulate<Ch>:PARameter:MEASure
, but in presence of balanced ports
this command distinguishes between
●
single-ended S-parameters for logical ports (
SSS<Li><Lj>
)
●
"raw" single-ended S-parameters referring to physical ports (
S<Pi><Pj>
)
Suffix:
<Ch>
.
Channel number
Setting parameters:
<TraceName> Trace name
<Result> Measured quantity
Manual operation: See "S-Parameter" on page 437
CALCulate<Ch>:PARameter:SDEFine <TraceName>, <Result>
Creates a trace and assigns a channel number, a name and a measurement parame-
ter to it. The trace becomes the active trace in the channel but is not displayed.
